Google and Mozilla are now working on adding file-/protocol-associations to webapps. So that when you want to select an image. You can browse your filesystem or use webapps that registered with your browser: One more item which is needed to make the web into an operating system.

Me too, especially that I think in this case, there could be a dependency problem. I mean, if you read the article, they use a web app that shortens URLs. So your main application needs this app to work, but if you haven't registered the URL-shortening app, then you might get an error, correct? Or I didn't get the whole concept? This is getting a real mess...
